What are the characteristics of the Automotive Wiring Harness Protection Sleeve?

Automotive Wiring Harness Protection Sleeve are widely used in industrial machinery, aviation, automobiles, electronics, construction, medicine, chemicals, food and other industries. parts and other optimal Cable Sleeve materials. So what are its characteristics?

1. Heat resistance: The Automotive Wiring Harness Protection Sleeve has much better heat resistance than ordinary Cable Sleeve, and can be used almost forever at 150 degrees without performance change; it can be used continuously for 10,000 hours at 200 degrees; It can also be used for a period of time at 350 degrees.
2. Cold resistance: the delay of ordinary Cable Sleeve is -20 degrees to -30 degrees, that is, the protective sleeve of automobile wiring harness still has good elasticity at -60 degrees to -70 degrees. Also withstands very low temperatures.
3. Weather resistance: Ordinary Cable Sleeve are rapidly degraded under the action of ozone generated by corona discharge, while Automotive Wiring Harness Protection Sleeve are not affected by ozone. And under ultraviolet light and other climatic conditions for a long time, its physical properties will only change slightly.
4. Electrical properties: The Automotive Wiring Harness Protection Sleeve has a high resistivity and its resistance value remains stable in a wide temperature and frequency range. At the same time, the Automotive Wiring Harness Protection Sleeve has good resistance to high-voltage corona discharge and arc discharge.
5. Conductivity: When conductive fillers (such as carbon black) are added, the Automotive Wiring Harness Protection Sleeve will have conductivity.
6. Thermal conductivity: When some thermal conductive fillers are added, the Automotive Wiring Harness Protection Sleeve will have thermal conductivity.
7. Radiation resistance: The radiation resistance of the Automotive Wiring Harness Protection Sleeve containing phenyl is greatly improved.
8. Flame retardancy: The Automotive Wiring Harness Protection Sleeve itself is flammable, but when a small amount of flame retardant is added, it has flame retardancy and self-extinguishing properties; and because the Automotive Wiring Harness Protection Sleeve does not contain organic halides, it does not emit smoke when burning or release poisonous gas.
9. Air permeability: The protective film of automobile wiring harness has better air permeability than ordinary Cable Sleeve and plastic waxed film. Another feature is that it has strong selectivity to different air permeability.
Advantages: Can be used in the working environment of -60℃~+200℃ for a long time, transparent, non-toxic, odorless, good insulation performance, good processing performance, disadvantages: poor wear resistance, tear resistance, oil resistance, and chemical medium resistance. Widely used in electric heating appliances, electronic and electrical industries, aviation, national defense, machinery, construction industry, medical treatment, food, hygiene fields, as well as kitchen supplies, household daily miscellaneous products, etc.
